abstract
A self-locking automatic spraying device consists of a cylinder (12), a water press (1), a water press seat (2), a water inlet elbow (3), a self-locking valve (5), a four-way (6), a three-way (7), an explosion-proof head (8) and a water outlet connector (9). The cylinder (1 1) is internally provided with more than one liner (1 1), which is vertically connected with a rubber tube (14), and the upper ends are respectively connected with a pressure gauge (13) and a pressure reducing valve. The spray device does not need to use the handle to compress air when spraying medicine, and there is no dripping phenomenon. After spraying the liquid medicine, the self-locking device automatically locks the valve.
The patent number is true, but there is still a problem you should think clearly. 1. A patent number may not be effective. For example, I applied for a patent for electric light, and even if I can only save one tenth of the power consumption of electric light, I can get a patent, but this technology has no practical value at all, understand? 2. The patent is true, but it is not necessarily produced by a regular factory. It is probably made by a cottage factory, because patent protection in China is almost blank now.
